I've had the new M&K 2in 1out exhaust on my freshly rebuilt 2.7 CIS for about a week now. I did the install myself with a pair of like new SSI's at the same time. It was a pretty straightforward operation because of the fresh rebuild (no rust/exhaust bolt problems thankfully). I'm digging the increased power and the sweet sounds for sure. I did a 15 second MPEG of audio and video. The glasses in the shot have tiny binaural microphones attached to them (I rigged up for "bootlegging" a few years ago - private use only on the music - but if you like Trailer Bride or 16 Horsepower - I may be your new best friend). I'm recording MPEG to Memorystick and then uploading to YouTube - so the compression of the file really didn't justify worrying about the sound quality in the end anyway. I uploaded the file to my own webspace intially and realized why the guys who started YouTube started YouTube - uploading video and pasting links isn't seemless. So I now have my first video at YouTube. Yikes.
